UNITED STATS aizzai oFFlC The present invention relates to new and useful improvements in the art of making glass articles, and more particularly to an apparatus for making toy glass marbles, and has for its primary object to improve the construction of machines whereby to increase the production thereof.

A further important object of the invention is to provide a novel shearing mechanism for cutting the globules c-f molten glass to form the marblesl and embodying a shearing device capable of increasing the number of marbles cut from the molten mass and also providing tiltable chutes receiving the marbles from the discharge Tunnels, the chutes being actuated for conveying the marbles alternately to separate rolling machines whereby to prevent contact of the marbles with each other during the rolling action.

A still further object of the invention is to provide an apparatus of this character of simple and practical construction, which is efficient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the de tails of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view with parts broken away and shown in section.

Figure 2 is a vertical sectional view taken approximately on the line 2-2 of Figure 5 illustrating the shearing mechanism with one of the end knives in cutting position.

Figure 3 is a similar view showing the center knife in cutting position.

Figure 4 is a similar view showing the other end knife in cutting position.

Figure 5 is a horizontal sectional view taken substantially on a line 5--5 of Figure 1.

Figure 6 is a fragmentary vertical sectional View taken substantially on a line 6-6 of Figure 1.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a suitable glass furnace within which glass of one or more colors is adapted to be melted, the resultant stream B gravitating downwardly through an opening (not shown) in the bottom of the furnace. I

Positioned below the furnace 5 is a cutter guide designated generally at 1 having an opening 8 extending horizontally therethrough of substan- 2 Claims. (Cl. 49-14) tially rectangular shape in vcross section to den a top section 9 and a bottornseotion Ill, the top sections having a cup I'I formed therein positioned in the path of ow of the molten glass E and into which the" glass is' deposited from the furnace.

The bottom section I0 is formed with a pair of spaced funnels I2 and I3 offset from the cup II at opposite sides thereof.

A cutter bar I4 is slidably mounted in the opening 8 and is reciprocably actuated by a rod I5 attached thereto and operatively connected to a suitable operating mechanism (not shown).

The cutter I4 is formed with a front cup I6, a rear cup I'I and an intermediate cup IB. Recessed in the upper surface of the cutter bar I4 immediately above each of the cups therein is a circular beveled knife I3 .adapted to shear a globule 20 from the bottom of the molten mass E as the same gravitates through the cup I I yinto one of the cups of the cutter bar.

A plate 2I is supported beneath the guide'l, the plate having discharge openings 22 and 23 therein, a pair of such openings being provided adjacent the funnels I2 and I3.

Chutes 24 and 25 are positioned immediately beneath the funnels I2 and I3, respectively, each of the chutes being rockably supportedon a pin 26 carried by the plate 2l at a point between the openings 22 and 23,the ends of the chutes being positioned immediately above said openings.

The chute 24 is operated by an actuating mech.- anism which comprises an upstanding arm 21, secured to one end of the pin 26 and to which a link 28 is pivotally attached at one end and t0 the other end of which is pivotally attached the lower end of a trip lever 29 which extends verti cally and is pivotally attached, as at 35, to the side of the guide l. The chute 25 is likewise op erated by a similar actuating mechanism come prising an upstanding arm 21 secured to `one end of the pin 25 and to which a link 28,v is pivotally attached at one end and to the other end of which is pivotally attached the lower end of a trip lever 29 which extends'vertically and is pivotally attached, as at 33', to the complemental side of the guide 1.

A cam bar 3l is formed on one side of the cutter bar I4 and projects outwardly through the side of the guide 'I' through a slot 32., the outer edge of thecam bar 3I having the toothed formations 33 thereon forming the cam hump engageable with the upper end of the lever 29 to actuate the lever toproduce a tilting movement of the chutes 2 4 and 25 during the reciprocating action of the cutter bar I4. The chute 24 is tilted from the position indicated by the full lines in Figure 6 to the position indicated by the dotted lines in said ligure by the toothed formation 33 of the cam bar. The chute 25 is likewise tilted from the position indicated by the full lines in Figure 6 to the position indicated by the dotted lines in said figure by the complemental toothed formation 33 of the cam bar. The chutes 24 and 25 are returned to the full line-positions 'by vany suitable means, not shown.

Positioned immediately beneath the discharge openings 22 and 23 in the plate 2I are the marble 4 globule is deposited therethrough onto the chute for feeding to the inner ends of the oppositely directed grooved ends 35b of the rollers 35 of the rolling machine.

During the rearward movement of the cutter bar I4, the center cup I 8 likewise receives one of the globules and deposits the same into the funnel I3 for subsequent deposit onto the inner ends of the rollers 34, the center cup I8 thus feeding the globule to both the fiinjnels lf2 and I3 while the front-cup IIifeeds `the'gloleules only to the funnel I2 and the rear cup II feeds the ."globules only to the funnel I3.

rolling machines, composed of pairs .of helically grooved complemental spaced rollers'and" 35. Each of the pairs of rollers 35 is provided 'with oppositely directed grooved ends, `only one ofv such rollers being shown in Figures r1 to inclusive, the respective grooved ends being indicated by the numerals 35a and 35h. Each pair of the rollers 34 is similarly provided with oppositely directed' grooved ends 'of like conguration; not shown. The 'globules of 'material are 'deposited onto the rollers by .the 'respective chutes 2,4y and 25 'adjacentthe center of the rollers and are caused, through the intermediacy vof the Aoppor sitely directed grooves, to be fed toward theends thereof.

In the operation' of the dfevicejand with the parts shown in the positions "shown in Figure 2 of thel drawings, ,theV molten lglass will `be deposited through thc cup II into the front cup I5 of the cutter' 'bar' Iii'whereby'a forward movement of the cutter lbar willsever the glo'bu1e720 at the lower end of the molten mass and deposit the same in the bottom'of the Icup I6, as shown bythe A,ol-'oitt'fed lines. i/VhentheA front cup I6 passes 'over the funnel I2,`as shown inV Figure 3, the globule will thenjbe 'deposite-d1 through the llnllel onto the chute-24 and fromrthe chute the globule will be deposited ronto the inner end of the oppositely directed "groovcd lenlds'fSll'ofv the rollersf'3'5of Ythe rolling' machine which fun-y t to 'Continuously twirl and krieg@ the 'globglle end at the same time conveys Vthe samge longitudinally YSo that by the time it reacheslthe dischargeend of` 'the `marble 'rollingmachine '1 is perfectly Sen-near hardened anni readyforA use, #Subiect 'lfilv'tg'l'igf-V n the front cup I6 reaches the funnell I'2, thecentercup :Ifjwill then-b'e positienedbeneath the 'ci-ip "II ""fo-r likewisereceiving oue 'of the gl'cbu'ieswl hf'is-jcutfbya further forward Inovementfof the cutterba I-'II deposited in @the cup-gig ffgm'wnich it terrien-'delegated in the fun-ngel IZg'as"shownfinfligue 4 of the 'drawings During this a n theain bar 3l x'fi-motiens to ftriptheehute frontline full line position shown in Figure f6 -totlie4 dotted 'line 'position whereby lt ejg'lobu-le isY then discharged 4vtinto the inner ends f -thecinplementa'l `opposit ely directedfgroovedf'endsof the Arollers 134 of the trolling machine.
